unable to send group chat invitation on gmail/aim/icq

[Siddharth Chandra]

Hi,
I am unable to send group chat invitation on gmail/aim/icq protocols.
I use the following APIs in the nullclient code provided by libpurple.

PurpleConversation *new_conv;
PurpleConvChat *new_chat;

new_conv = purple_conversation_new(PURPLE_CONV_TYPE_CHAT, account,
chatroom_name);
new_chat = purple_conversation_get_chat_data (new_conv);
purple_conv_chat_invite_user(new_chat, buddy_name, msg, FALSE);


This works well with msn and yahoo.

Please help me out,
Thanks in advance,
Siddharth
